I am in 9th class my exams are going to start so i need everyones help in solving these questions.
I have written square root 2 , square root 3
square root 3x
Question 1)2x + √2 = 3x -4 -3√2
Question 2)√3x - 2 = 2√3 + 4

Hi prashant,
Welcome to the forum
Always specify the problem completely. Here you want to us to solve for x, right?
Q1)
$\displaystyle 2x + \sqrt{2} = 3x -4 -3\sqrt{2}$
Subtract 2x on both sides:
$\displaystyle \sqrt{2} = 3x-2x -4 -3\sqrt{2} = x - 4 - 3\sqrt{2}$
Add $\displaystyle 3\sqrt{2} + 4$ on both sides:
$\displaystyle 4+3\sqrt{2}+\sqrt{2} = x$
Now remember that $\displaystyle 3\sqrt{2}+\sqrt{2} = (3+1)\sqrt{2} = 4\sqrt{2}$
$\displaystyle x = 4 + 4\sqrt{2}$
Q2) it is similar to the above. You try to work it out and post your work here. We will help you if you get stuck.
